7000 SERIES CLOSED TRANSITION AUTOMATIC TRANSFER SWITCH |
ASCO Automatic Closed-Transition Transfer Switches feature main
contacts that overlap, permitting the transfer of electrical
loads without power interruption. The switch transfers in a
make-before-break mode if both sources are within acceptable
parameters. Control logic continuously monitors source
conditions and automatically determines whether the load
transfer should be open (conventional non-overlap mode) or
closed transition. Available 150 through 4000 amperes.
Closed-Transition Transfer within 5 electrical degrees is
achieved passively, without control of the engine generator set.
Therefore, no additional control wire runs are required between
the ATS and engine generator set governor. Plus, protective
relaying may not be required under normal operation since the
contact overlap time is less than 100 milliseconds (consult your
local utility on protective relay requirements).
Failure to synchronize indication and extended parallel time
protection is built-in to all 7000 Series closed transition
controls to prevent abnormal operation |
